The GMC Syclone is a high-performance version of the GMC Sonoma pickup truck. Produced in 1991 by GMC, the Syclone spawned the similarly powered 1992-1993 GMC Typhoon SUV. Another vehicle, the GMC Sonoma GT, offered less performance but was seen as a companion model.
At the time it was introduced, the Syclone was the quickest stock pickup truck being produced in the world. Auto magazines compared its acceleration favorably to a variety of sports cars including the Corvette and - in a memorable comparison test in Car and Driver magazine - a Ferrari. Featuring a turbocharged 6-cylinder engine, all wheel drive, and 4 wheel anti-lock brakes, the specifications had more in common with a Porsche than most other pickup trucks.
Trucks were built PAS in Michigan. PAS was also tasked to build the 20th anniversary turbo trans am
Both the Syclone and Typhoon trucks featured a Mitsubishi TD06-17C 8 cm² turbocharger and Garrett water/air intercooler attached to a 4.3 L LB4 V6 engine with unique pistons, main caps, head gaskets, intake manifolds, fuel system, exhaust manifolds, and a 48mm twin bore throttle body from the 5.7 L GM Small-Block engine. All Syclones and Typhoons had a GM 700R4 4-speed automatic transmission. A Borg Warner all wheel drive transfer case split torque with 35% forward and 65% to the rear wheels. Both trucks featured sport modifications to the standard suspensions. The Syclone was the first production truck to receive a 4-wheel anti-lock braking system. Output was 280 hp (209 kW) and 350 lb·ft (475 N·m). The Syclone, when new, was capable of accelerating from 0-60 mph in 5.3 seconds and could do a quarter-mile run in 14.1 seconds at 93 mph (150 km/h) according to Car & Driver's comparison test.
